雅思小作文图表中极少会考到单个饼图，但是无论是两个饼图，还是三个、四个饼图，在考试时间极其有限的情况下，发现和总结规律是应对饼图的关键。

例如下图所示（以主体段为例分析）

The charts below show US spending patterns from 1966 to 1996.

应对饼图，我们只需采用以下三个解题步骤（我称它为"饼图三步曲"）

1）Present a Clear Overview 展示清晰的概貌

具体而言，观察每张饼图的各类别所占比例，并比较两幅图之间的关系。不难发现在这两个年份food和cars是占家庭支出的最大的两个类别并且food和cars的总和占家庭支出比例的半数以上。具体表达如下：

Food and cars made up the two biggest items of expenditure in both years. Together they comprised over half of household spending. Food accounted for 44% of spending in 1966, but this dropped by two thirds to 14% in 1996. However, the outlay on cars almost doubled, rising from 23% in 1966 to 45% in 1996.

2）Summarise Main Features 总结主要特征

比较相同类别在各饼图之间的比例变化（涉及趋势变化）。

除去food和cars，剩余的5类所占家庭支出的比例变化有上升也有下降趋势，有变化幅度大的也有变化幅度小的。如：

restaurants:  7%----14%

computers:  1%----10%

books:  6%----1%

petrol:  9%----8%

furniture：10%----8%

3) Make comparisons where relevant 相关数据作比较

理论上而言，按趋势和幅度分段写都是可以的，但为了数据信息处理更简便以及使表达上更精炼，我们在这里按变化幅度分段描述。

A． 变化幅度大的有restaurants, computers和books

Some areas changed significantly. Spending on restaurants doubled, climbing from 7% to 14%. The proportion of salary spent on computers increased dramatically from 1% in 1966 to 10% in 1996. However, as computer expenditure rose, the percentage of outlay on books plunged from 6% to 1%.

B． 变化幅度小的有petrol和furniture

Other areas remained relatively unchanged. Americans spent approximately the same amount of salary on petrol and furniture in both years.

因此，无论考试中遇到几个饼图，掌握了以上针对饼图的解题技巧，"以不变应万变"，饼图便可迎刃而解。
